Can you use the original chain links with the repop housing? Seems like original housings have a steel inner lining the chain links run in, no mention of that being in the new ones. I know they sell a modern cable kit for them but I don't usually care to use new "improved" parts. I guess the outside housing would be ok but I'd rather use the stock internals.

you can use repop housing but must be aware that the chain could become disengaged by having too much clearance. i put a nylon tube inside the repop housing to give the proper clearance for the chain. note also the repop housing is smaller in o.d. than the original.

Cory-
I used reproduction ends on my original speedometer flexible shaft. As Stuart says, there needs to be a bushing made and inserted so that the drive ends have the proper fit.

I made mine out of brass:


Here is the end without the bushing:


Here it is with the bushing in place:


Here is a cutaway diagram of the flexible shaft and chain:


I also re-shaped the end of the knurl to make it look right for my 1911. Here is the reproduction end, the end I modified, and an original:


For your 1914 I believe the drive end would have the hex nut and the speedometer end has the knurl.

If the original chain won't work with the reproduction flexible shaft, for $50 more you can get the cable that is designed to go in it.

" REPOP" sounds like a bad batch of popcorn.

OK, thanks. Now I've got a better idea. I'm not in a hurry, been driving 20 years without one, but I got a speedometer head, a wheel gear and a swivel so if I can come across the rest eventually then I'll know. And I never cared for "repop" I think "repro" sounds better but "repop" seems to be used more.
